Tailscale Server Builder Flatcar Linux needs first-boot Ignition userdata. This browser tool generates it and configures Tailscale as an exit node.

Server settings

Paste a Tailscale auth key, choose a provider, then copy the Ignition config.

Tailscale key required
Provider
Which provider should I pick?
Vultr
Lowest friction because Flatcar is selectable when creating a server.
DigitalOcean
Good if you already use it, but you need to import a Flatcar custom image first.
Hetzner
Often cost-effective, especially in Europe, but setup is more involved and starts with a snapshot.

Generated output

Copy is the usual path. Download only if the provider asks for a file.
